I'd like to create a new Sitecore item using a name that contains German characters. At the moment every time the name contains "ä" "ö" or "ü" Sitecore complains about the name and prevents me from creating it.
I can see the same problem using the EXM module (E-mail Experience Manager). I cannot create any newsletters that contain special characters.
Is there any way I could change it?
The problem is caused by the regular expression which is used for the "Name" field validation.
You can resolve the issue by replacing the ItemNameValidation
setting value with the following value:
^[\w\*\$]*[a-zA-ZäöüßÄÖÜẞ\][\w\s\-\$]*(\(\d{1,}\)){0,1}$
or add a new patch config file to your project which is recomended.
<setting name="ItemNameValidation" set:value="^[\w\*\$]*[a-zA-ZäöüßÄÖÜẞ\][\w\s\-\$]*(\(\d{1,}\)){0,1}$" />
